I've long argued\n\u003e\u003e that a zero-output transaction should be permitted -- 100% miner fee\n\u003e\u003e -- as an elegant proof of sacrifice.  Unfortunately that requires a\n\u003e\u003e hard fork.  Also, for most people, it seems likely that a change\n\u003e\u003e transaction would be generated.  That, then, would generate an\n\u003e\u003e already-standard transaction, where inputs \u003e outputs.\n\u003e\n\u003e 100% miner fee is not a proof of anything because the miner could have created\n\u003e that transaction for themselves. You must have proof that all miners had an\n\u003e equal opportunity at collecting the fee, and the only way to do that is by\n\u003e Peter's announce-commit protocol, or his unspendable until after n blocks\n\u003e proposal.\n\nAbsolutely.  It wholly depends on the security model, and\neconomic-incentives model.  Some use models simply don't care if the\nminer created a transaction that gave the fee to themselves.  It might\neven be /encouraged/ to do this!  Sure they are paying themselves, but\ngiven bitcoin network difficulty is so high, simply obtaining\npayments-go-myself-as-miner transactions is itself difficult.\nProducing an identity (my goal) or whatever is just fine, and in such\ncase becomes simply an additional block reward -- an additional\nincentive to buy into this identity creation/management system.\n\nOr exchange \"identity\" with another token, for another data service of\nyour choice.\n\nThis is no longer a strict \"proof of sacrifice\" system, if such\nbehavior is encouraged, but it is nonetheless valid.\n\n-- \nJeff Garzik\nSenior Software Engineer and open source evangelist\nBitPay, Inc.      https://bitpay.com/"}
